ZZZ/676257" LULOFF WIL SON, OF CHICAGO, ILLINOIS.

v ROLLER-BEARING.

Application filed December 18, 1918. Serial No. 267,307.

To all whom it may concern:

Be it known that I, Lunorr WnsoN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and usefullmprovements in Roller-Bearings, of-

which the Yfollowin is a specification.

My invention re ates to improvements in roller bearings and has especialreference to means for holding the rollers properly spaced apart and inaxial alinement, Wltllout clamping the rollers and ,without imposingundue. friction to resist rotation thereof. a I One of the objects of myinvention is to improve structures of this character by providing aroller-holding cage or carriage that will allow limited movement of the.rollers in every directionwithout permitting them to move materially outof axial alinement or out of the ca e.

Another ob ect of my invention is to simplify and cheapentheconstructiom I Other and further objects of my invention will becomereadily apparent to persons skilled in the art, from a consideration of.

the following description when taken in conjunction with the drawings,w,here1n Figure 1 is an end view of a bearing member of a generalconical form, looklng at the lar er end, showing parts broken away.

ig. 2 is a fragmentary section taken on line 22 of Fig. 1. I

Fig. 3 is an enlarged fragmentary v1ew 1n section, taken on line 3- 3 ofFig. 2.

Fig. 4 shows face views of a modificatlon of my invention, as applied toa thrust bear- 1n ig. 5 is a perspective view of a rollerholding wing,for pivotal engagement with the cage frame.

Fig. 6 is an enlarged section, taken on permissible ing a radiallyprojecting larger flange 13.

Openings 14 are made at Intervals between Specification of LettersPatent.

the rings, leaving connecting bars 15, thereto join the rings together.WVhen the improvement is to be applied to a thrust bearing, the cageframe 10 may be made in disk form, as shown in Figs. 1 and 6, providedwith openings 14 and 14 as the case may be, the former for a pluralityof roller sections of uniform diameter, and the latter for taperedrollers as common in structures of this character. 1

A roller retaining wing 20,'transversely curved, is provided at its endswith notches 21, which notches hold the wing properly in place andpermit slight rotary movement on its longest axis, when the said notchesengage the respective parts of the frame on either side of the openings14 and 14. Midway of the narrowest dimensions of the openings 14:, arenotches 22, which are sufficiently wide to permit insertion of therollers, the wings are p ced in the notches 22 until the notches 21 ofthe wings are in register with the notches 22, whereuponthe wings arethen slipped down to their proper positions in substantial contact withthe cross members 15 and 15. After the wings have been placed inposition, they are moved as much as may be, as shown in dotted lines inFig. 6, whereupon the rollers 23 are position against the resiliency ofthe wing structure, 'and'the rollers will thereupon snap into place, asclearly shown in Fig. 3. The notches 22 are not necessarily. required asthewings may be placed diagonally of the openings 14 and the notches 21-may then be placed astride the horizontal legs of the rings 11 and 12.2 1 and 25 are the other bearing members upon which the rollers. move,and which are common in structures of this character. I I

In Fig. 4 I have shown tapered rollers 23 in assoc1ati'on with the samesort of wings 20, that are placed in tapered slots in the disk 10'. Ihave also shown composite rollers '23 made up of a number of sectionaldisk members, all of which are properly held 'in the cage by thepartially encompassing F om the foregoing description, it will bemanifest that my improved means .of holding the rollers is as welladapted for bear- I ing structures intended for shafts of uni formdiameter, in which case the rings 11 and 12 will be of the same diameterinstead 7 a cage frame,

of holding the rollers. angularly disposed with reference to the axis ofthe shaft, as shown in. Fig. 2.

Having described my claim is 1. A roller bearing having in combination acage frame, provided with roller-containinvention, what I ing openings;a pair of transversely curved wings, pivoted in each saidopenmg, and aroller between wings of each pair.

2. A roller bearing havlng in combination provided withroller-containing openings; a pair of transversely curved,

, ing openings; a pair resilient wings, pivoted in each opening andhaving limited free movement, and a roller between the wings of eachpair of a diameter requiring flexing of the wings to permit itsinsertion. t

3. A roller bearing having in combination through said-notches andhaving notches in their ends to engage the walls of the respectiveopenings to permit limited pivotal movement of the wings and a rollerbetween the wings of a glven opening.

5'. A roller bearing having in combination I two rings, each ring havingan angular cross section with horizontal legs facing each other;spaced-apart bars holding the rings in spaced relation, and leavingopenings therebetween for rollers; transversely curved wings havingnotches in each end, to engage'the horizontal legs of the respectivewings to hold them limited pivotal movement thereof, and a rollerbetween the wings of a given opening.

6. A roller bearing having in combination two rings, each ring having anangular cross section with the horizontal legs of the two rings facingeach other; integral spaced apart bars, oining the horizontal legs andholding the rings in spaced relation and leaving openings therebetweenfor rollers; transversely curved wings having notches in the mid-portionof each end to engage the horizontal legs of the respective wings tohold the wings in place and to permit limited pivotal movement and aroller between the wingsof a given opening.

In testimony whereof I hereunto subscribe my name.
